Filed: 1921-09-30
Abstract: 191,127. V.M.L. Experimental, Ltd., and Lucas, O. D. Sept. 30, 1921. Fire between aircraft propeller blades, controlling and synchronizing.-Relates to electrical means for firing under the influence of a commutator on the propeller shaft and a contact controlled by the closure of the breech mechanism. According to the invention, the instant of firing is determined by the position of the propeller blades in conjunction with the position of the breech mechanism, but the duration of the firing current is independent of these positions, being determined solelv by the time taken to fire the cartridge electrically or to release a striker electromagnetically. The electrical connections shown comprise a firing circuit through the cartridge. b<1> and a controlling circuit through a coil C<1>, both fed by a source of current D. The firing circuit is completed by a spring-controlled switch-arm C but is broken when the coil C<1> is excited by the closure of either a breech-contact b or a contact a<1> made by an arm A<1> operated by a disc A on the propeller shaft. In the " ready to fire " position shown in Fig. 1, the moving part B' of the breech mechanism has opened the contact b and the notch x in the disc A has opened the contact a<1>, the switch C therefore completes the the firing circuit which remains closed until the contact is made by the recoil of the gun. A firing key, shown in the inoperative position in Fig. 5, is operated by rotating a hub E and has a contact e connected to the controlling circuit through the coil C<1> and a contact e<1> in the firing circuit. On turning the key to the firing position the contact c is first closed to energize the coil C', further movement closing the contact e<1> and opening the contact e.

Abstract: 150,963. John, F. Sept. 11, 1919, [Convention date]. Clutches, claw and ratchet.-In positive clutches of the rotary-key type, in which overrunning of the driven member on engagement is prevented by a simultaneously engaging detent, interconnecting means are provided between the key and detent for holding the latter disengaged when the key is disengaged, in order to prevent wear and noise, and means are also provided for holding out of action the detent, key, and interconnecting device independently. The boss b<1> of a belt-driven pulley has secured within it a bush b mounted on a driven shaft a, in which lies a segmental key c, rotatably operable by a spring-pressed arm c' to engage one of the complementary grooves c<2> in the bush b when released by depression of the stop-lever d<1> actuated by treadle &c. A spring-pressed detent e, which also may be a rotary key, is positioned to engage one of the ratchet-notches e<1> in an extension of, or in a ring secured to, the boss b<1>, but is held out by a spring-pressed pawl h, which engages a nose e<4> thereon, and at its other end, a flat h<3> on the key c, so that engagement resets the pawl, the consequent overrunning of the part b<1> returning the detent. The pivots of the parts h, e and an extension of the key c bear in a cap secured to the end of the shaft a by keys f<1> which cap has a detachable cover-plate, through which project the squared spindle-ends e<3>, h<4>, and c<4>, and wherein holes i, j, k are formed for the insertion of locking-pins. If the key c is locked inoperatively, accidental engagement of the clutch is impossible, and, if the driven machine become jammed, the pulley may be reversed, then stopped, and the pawl manually operated to release the detent, which, on restarting the pulley backwardly, engages a notch with an impact tending to free the machine. For facilitating setting machine-tools, the pawl h may also be looked inoperatively, whereby intermittent backward impacts may be given by manual or power operation of the driving-member, or a similar forward step-by-step drive may be given if the key c alone is left free to act as a ratchet.
